Black Bolt: The King (Anson Mount)

His voice is so powerful that a whisper can level a city, which makes it a particular challenge for any actor to communicate without dialogue. Part of the solution? Mount created his own form of sign language based, in part, on ASL.

'Marvel's Inhumans': Check out 7 new character posters

As the premiere of Marvel’s Inhumans approaches, we’re getting glimpses of the characters in all their glory. The king of the Inhumans, Black Bolt finds himself stranded on Earth after a coup led by his brother, Maximus. Black Bolt must now reclaim his throne with the help of the rest of the royal family: Medusa, Crystal, Gorgon, Karnak, and Triton. Much of the series was shot on IMAX cameras and Marvel is hoping the epic visuals will separate Inhumans from the growing number of comic-book films currently on television.
